Final answer:
Autism spectrum disorder (ASD) may result from abnormal development of the corpus callosum, which is responsible for communication between the brain hemispheres.
Step-by-step explanation:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that research suggests may result from abnormal development of the corpus callosum. The corpus callosum is a bundle of nerve fibers that connects the left and right hemispheres of the brain, allowing communication between them. When the corpus callosum is abnormal, it can lead to impaired social interaction and communication abilities, which are characteristic symptoms of ASD.
